Definitions

  • WO 2018/125933 describes a system for preserving cut plants, the system comprising:
  • a gel media at a bottom of the container said gel media comprising a hydrophilic gel selected from the group consisting of: a polyacrylamide and an agarose; and,
  • aqueous liquid comprising 0.001-30 M of one or more destabilizing agents selected from acidulants, dissolved metal cations and dissolved ammonium cations; and/or 0.1-70 wt.% of nutrients; and
  • the present method offers the advantage that due to the thixotropic nature of the aqueous gel ingredients such as the aforementioned destabilizing agents, but also other components, such as nutrients, can be introduced to form a hydration medium that is ready for use. This provides the end user with the flexibility to formulate the hydration medium according to his/her needs.
  • the aqueous liquid may suitably contain a dissolved metal cations as the destabilizing agent.
  • the aqueous liquid contains 0.005-30 M, more preferably 0.015-25 M and most preferably 0.025-20 M of the dissolved metal cations.
  • the aqueous liquid contains 0.005-30 M, more preferably 0.015-25 M and most preferably 0.025-20 M of dissolved cations of metals selected from alkali metal, alkaline earth metal, aluminium, bismuth, boron, zinc, manganese, iron copper, nickel, cobalt and combinations thereof.
  • the aqueous liquid contains 0.5-40 wt.%, more preferably 1-20 wt.% and most preferably 2-10 wt.% of surfactant selected from nonionic surfactant, anionic surfactant, amphoteric surfactant and combinations thereof.
  • Yet another aspect of the invention relates to a method of preparing a gelled hydration medium, said method comprising:
  • the different flower gels were produced by separately preparing a thixotropic smectic clay gel and 7 different aqueous liquids.
  • the thixotropic smectic clay gel was prepared by mixing 20 grams of smectic clay clay with 970 grams of tap water.
  • the aqueous liquids were prepared by mixing the remaining ingredients with the rest of the tap water.
  • the flower gels were prepared by stirring the thixotropic smectic clay gel with Silverson L4RT High Shear Mixer to liquefy the gel. Then, the aqueous liquid was added, followed by 5 minutes of mixing.
  • the rheological properties of the thixotropic smectic clay gel were determined 48 hours after preparation, using a Brookfield CAP 2000+ viscometer as described herein before. The results are shown in Table 2
  • Example 2 Tests were carried out in which the stems of cut roses were immersed in flower gels of different compositions and in which the ensuing effect on attractive flower life was determined.
  • the thixotropic smectic clay gel was liquefied by stirring the gel with a Silverson L4RT High Shear Mixer, and flower gels were prepare by adding aqueous liquid (water or citric acid solution), followed by 5 more minutes of stirring.
  • aqueous liquid water or citric acid solution
  • the viscosities of the different flower gels were measured as described in Example 1 , 2 days after production. The results are shown in Table 18.
  • the thixotropic smectic clay gel was liquefied by stirring the gel with a Silverson L4RT High Shear Mixer, and flower gels were prepare by adding aqueous liquid (water or aluminium sulphate solution), followed by 5 more minutes of stirring

Abstract

L'invention concerne un kit d'expédition de fleurs comprenant : ° un récipient contenant un gel de fleur aqueux ; et ° une ou plusieurs fleurs coupées dont les tiges sont immergées dans le gel de fleur aqueux ; ° le gel de fleur aqueux comprenant (i) 1 à 4 % en poids de nanoparticules d'argile smectite en forme de disque ayant deux surfaces plates opposées qui sont chargées négativement et un rebord qui est chargé positivement, et (ii) 0,01 à 250 mM d'un ou de plusieurs agents de déstabilisation de gel choisis parmi des acidulants, des cations métalliques dissous et des cations d'ammonium dissous. Le gel de fleur de la présente invention libère lentement de l'eau au cours du temps d'une manière qui permet aux fleurs coupées de l'absorber immédiatement. L'invention concerne également un kit de pièces pour la préparation d'un milieu d'hydratation gélifié et un procédé de préparation d'un tel milieu d'hydratation gélifié.
